With the introduction of new technical requirements to models-copies category S5 most preferred as a prototype steel two-stage rocket with large differences in diameters of the housings of the steps. This requirement well enough to answer the research rocket developed in the US on the basis of the accelerator anti-aircraft missiles “Nike” (“Nike-Tomogavk”, “Nike-Keygen”, “Nike-Apache” and others).
Readers are invited to description rockets “Nike Kigen” and its class model S5C, made in the scale 1:10,4775 (scale due to the adjustment of the diameter of the first stage up to 40 mm). The sample runs show that for this model, take-off height of 500 m is not the limit value.
At the request of the editors have prepared for you master of sports of the international class Vladimir Minakov and honored coach of the USSR S. Zhidkov.
The proposed model-copy two-stage: first stage with MRD 5-3-0, the second with MRD 5-3-6, though it may be a different combination of motors with total impulse of 10 N*s. All parts of the body and compartments is wound from fiberglass 0.025 mm four layers on the resin ED-20. Mandrel metal. Pre-heated and applied to the surface mastic “Edelvays”. When forming the crossing location must be podmochat to STEKLONiT.
After curing of the resin is the slight shift of wikileak, rough machining burrs and heat treatment for 2 hours at 120°C. the Final finishing of the surface on the lathe with emery paper of different grits.
The external surfaces of the cases are degreased and covered with two or three coats of the lacquer AK-20. After polishing, controlled by the sizes according to the thickness of the future of the paint layer is 0,05—0,07 mm. Body parts are cut to length. Subassembly — on epoxy glue such as an EAF or To a-153.
A model double-primed nitro with aluminum powder, then applied 2-3 coats of white nitroenamels. Among all the stages is scraping the surface with emery paper. The last layer of paint will not be processed. The polishing of intermediate coating is not less than an hour after their deposition as at the end of the drying lasts for 12 hours. Stabilizers covered by yellow and red enamels. The best results in quality coverage gives the spray “Airbrush”.
